COLLAPSIBLE SPINDLE FOR THE DYEING AND-ANALOGOUS TRE'ATMENT OF WOUND YARNs. I

i Application filed December'm, 1928, Serial No. 327,150, and in Great Britain July 28, 1927. v

'but with many kinds of yarn -notably linen -the said yarn contracts so much on being wetted that it is impossible to take the constricted Cheese from the tube or spindle.

It is the object of this invention to provide v means whereby cheeses may be easily slipped upon a spindle having a perforated 'sur ace and be ,easily removed therefrom after fluid treatment, no matter how great the con strietion of the cheeses which may' have occurred. A further object is to make these means of such a strong and simple Construction that the spindle will not be easily damaged or knocked out of order by rough han.- dling in the dyehouse or other place where it is used.

According to the invention the collapsible spindle is composed of a plurality of` perforated sections whichform the surface of the spindle each such section being movable radially of the spindle center;`a fixed central rod; and a sleeve slidable upon the said rod which sleeve is connected by links to each such perforated section; and links which act as distance pieces 'between the fixed central rod and each such section.

Sliding movement of the sleeve upon the rod will thus, through the medium of the' link connection between the said sleeve and the sections, cause the latter to move inwardly or outwardly, and the distance pieces, consisting of links will vary their angle to ensure that at all relative positions of the perforated sections and the fixed central rod they will be eflective for their purpose, and cause each section to move evenly radially as a whole. In its expanded or contracted position therefore the -spindle will be of the same diameter throughout its length.

Four perforated sections are found very convenient in practice, the longitudinal' edges of two diametrically opposed pairs slightly overlapping the adjacent edges of the other two diametrically opposed sections, and to operate controllably the sliding sleeve, ;a nutthreaded upon the fixed. central rod and engaging thesleeve by a collar rotatable with the'nut is found convenient and simple.

The s invention with arrangement of. Vdetails in a very convenient and practical form will now be fu'lly described, reference being had to the accompanyng drawings whereinz-- Figure 1 is a cross section partly in elevation of a spindle constructed according to' the invention; v

Figure 2 is a longitudinal section taken on line 2-2 of Figure 1; I

Figure 3 is a cross section taken online 3-3 of F igure 1; and

Figure 4 is a bottom View of the spindle showing the m'anner in which it is fitted to seatthe said spindle for use in a machine for d eing or analogous fluid treatment( 'Re erring tothe drawings, the surface ofthespindle is composed 'of four perforated sections 5, 6, 7 and 8 the longitudinal edges of the sections' 5 and 7 slightly overlapping the adjacent edges of the'sections 6 and 8 as clearly seen in Figures 2 and 3. The'base of thes'pi'ndle is, formed by a cylindrical member 9 and at the lower end of the said member spokes 10 are providedwith a central hub or boss 11 into which' is secured by the nut 12 the extremity of a rod 13 which forms the fixed central rod of the spindle and extends above the u'pper edges of the 'sections 5, 6, -7 and 8.' This rod is of round section where threaded to engage with the nut 12, of rectangular cros section `up to the point 14 of F igure l and from that point to its top is again of roundsection, part of which section isthreaded. a Upon the smooth round section at the upper part of the rod-is slidably fitted a sleeve 15 having at its lower portion the radial projecting member 16 and the saidsleeve is recessed and undercut as shown at 17 to receive rota'tably therein a collar 18 which fits rotatably upon the rod 13 and is formed solid with anut 19 placed upon the thread 'on the spindle so that the nut may be turned to move in either direction longitudinally of the said rod. Each of the perforated sections 5, 6, 7 and 8 has fitted` longitudinally and centrally thereof a stifening member 20 which 'may Conveniently be of channcl section as seen in Figures 2 and 3 and to the SOUTHPORT', AND' THOMAS BRANnwoon, OF nmen,

stiflening member 20 has linked thereto as.

shown at 23 the link pairs 24 the other end of each link being pvoted to a pivot' pin 25 passing through the fixed central rod 13. These link pairs 24 are in staggered relation as seen in Figure 1 and 'they act as distance pieces .between the central rod 13 and the particular section 5 6, 7 or 8 to which they are linked. As will be seen, the sections 5, 6, 7 and 8 being prevented by the controlled sleeve 15 and-the link pairs 22 from moving longitu'dinally of the fixed central rod 13 the link pairs 24 will act effectively as distance pieces at all radial posi-.

tions of these sections and at all variations to the horizontal of the angle of the said linked pairs 22. v

As in a treatment spindle of this character it is essential that fluid shall pass only through the perforations of'the surface and through the material mounted thereon, the spindle is closed at its upper end when in operation by a removable cap. Such a cap is shown in Figure 1, being of dished form at 26 and having a flange 27 which fits upon a packing ring 28 placed on the top of the cheeses y upon the spindle. The upper ex tremity of the fixed central rod 13 is formed as a threaded neck, upon which the cap, having a tapped central hole to correspond, may be screwed, a wing nut 29 holding it in this position. The spindle is thus open only at the bottom fluid gaining, ingress or egress between the spokes 10 of Figure 4, to the spindle, and through the material on the spindle and the perforations in the surface thereof.

In operation, when cheeses are to be placed upon the spindle the latter is first contracted, by turning the nut 19 so that it moves upwardly on the central rod 13 thus drawing upwardly the sleeve 15. The connected links 22 thus draw the sections 5, 6, 7 and 8 inwardly, adjacent edges thereof sliding over adjacent edges of other section, the distancing links 24 assuming an angle to the horizontal ;and each such section moving evenly and as a whole. t

The spindle being thus contracted, cheeses y are easily mounted thereon, the bore of the cheeses being of greater diameter than the now contracted spindle. Thisoperation of charging the cheeses upon the spindle with the bottom collar or 'ring 30 smilar rings interposed between the cheeses, and a top closer 28, may all be as described in our prior United States Letters Patent N o. 1,454,312.

The cheeses being mounted on the spindle, the nut 19 is now again rotated but in the reverse direction, and the sleeve 15 descends, thus by meansof the links 22 forcing the sections 5, 6, 7 and 8 outwardly, the distancing links 24 following this movement. The

cheeses being now tight upon the spindle as a result of the expanson of the latter, pressing of the charge of cheeses as described in our prior United States Letters Patent No. 1,454,312 may take place and when sufllciently pressed the cap 26 may be placed in position as described, and as .seen in the drawing, Figure 1. The spindle may then be screwed into a plate in the treatment apparatus and fluid under pressure passed through the bottom of the spindle, through the perforations in the surface and through the cheeses, this flow of fluid being reversed as desired, all as described in our prior United States Letters Patent No. 1,454,312.

To remove the' cheeses from the spindle after completion of the desired treatment, the cap 26 is removed and the nut`19 is again turned but in the reverse direction so that it, and the attached sleeve 15 ascend, thus through the medium of the link pairs 22 spindle and may' be easily removed for fur ther handling.

The sections 5, 6, 7 and 8 are of a non-` corrodible metal or alloy for instance nickel or nickel alloy, and the other parts may be of any non-corrodible' metal, or be coated withany such metal or with any anti-corrosion coating to prevent corrosion or the free movement thereof where movement is essential to the manipulation of the spindle.

We claim l. A spindle having a perforated surface composed of a plurality of ;parte arcuate in cross section and movable radially to the spindle center, a fixed central rod, a collar slidable upon the central rod and connected to the perforated parts by links, and further links acting as distance pieces between each such part and the fixed central rod.

2. A spindle as claimed in claim 1, the perforated surface consisting of four parts arcuate in cross section, the longitudinal edges of two diametrically opposed sections overlappin the adjacent longitudinal edges of the ot er two diametrcally opposed sections.

3. A spindle as 'claimed in claim 1, the

slidable collar upon the central rod being slidably operated by a nut threaded upon the fixed central red-and engaging by a collar rotatably held by the sliding sleeve. 4. A spindle as claimed in claim 1, the links acting as distance pieces being pivoted to the fixed central rod and to a strengthening and supporting rod fixed longitudinally and "centrally of each perforated section.

5. A spindle as claimed in claim 1, the

lower edges of the eperforated sections being movable in a recessed base and radially to the said recess.

6. A spindle as claimed in claim 1, and having also a base provided with a recess in which the lower portions of the perforated sections are movable radially, the'said base being provided with spokes and a central hub into whichthe fixed central rod of the spindle is screwed. w

7. In combination with a spindle as claimed in claim 1, a Closer cap adapted to screw upon the upper extremity of the fixed central `rod of the spindle to close such upper end when the material to be treated has been charged upon the spindle and the sections of the latte' expanded substantally as set forth.

In testimony whereof we have hereunto set our hands.
